HYDROCARBON-FURNACE Specification of Letters Patent. Patntgd SQP, 19, 1911,

Application filed April 29, 1911. Serial No. 624,045.

To allv whom t may concern:

Be it known that. I, JOHN C. SCRIVNER, a citizen ot' the 'United States, residing at Madison, in the county otl lvl'adison and State of lllinois, have invented certain new and useful Improvements in Hkvfdrocarbonli`urnaces, ot which the followingl is a specification, reference beingl had to the accompanying drawings.

My invention relates' to new and useful improvements,in furnaces and more particu-V larly to a hydro-carbon t'urnaee for metallurgical uses and my object is to provide a device ot this character in which there is provided a removable blast or bridge wall.

A further object ott' the invention resides in providing a furnace havingan arched top, which top is provided with a slot for the insertion' and removal ofthe bridge wall, and a urth'er object ot the invention resides in providing au elongated opening in the side ot the heating chamber ot the furnace through which the materials to be heated are inserted.

lVith these and other objects in view, my invention consists in the novel features ot' eonstruction, combination and arrangement ot parts as will be hereinafter referred to and more particularly pointed out.4 in the speeifieation and elaims.

ln the aeeompanying drawings 'forming a part ott' this application. Figure l is a side elevation o't.' my improved l'uruaee. Fig. 2 is a trout elevation thereof. Fig. 3 is a longitudinal sertion theretlu'ough, and, Fig. 'lis a transverse seetion of the same. Y

In earrying out my invention, l shall refer to the drawings in which similar reterenee eharaeters ldesignate eorrespomling parts throughout the several views and in which l indieates a base or Frame ot metal mounted on the supporting legs 2, upon which base or t'rame is mounted my improved t'urnaee which comprises a bottom, the vertical side walls 4 and 5, the short end walls ti and 7 and the arched top 8, all ot whit-h are t'ormed ot the usual or any prelerred form ot tire brick.

'lhe end or 'lront wall (3 of the, furnace is provided with anv opening, theI lower wall ot' whieh is buty a short distance above the bottom il ot' the tui-nare and extending within said opening, are the pipes t) and l0, the former heilig a blast or air pipe, while the .latter is an oil or hydro-carbon conduit, andthe oilpipe has mounted on, the end thereof extended within said furnace a shortdistance, the burner ll. As stated,- the, open f ing in the end wall of the furnace through which the burner ll extends, is positioned adjacent the bottom or floor of said furnace, and in this manner, it will be seen that; any oil or other hydro-carbon which may leak from said burner may be readily ignited before the same leaks from the bottom of the 'Furnace to the Hoor or ground of the struc: ture upon which said furnace is mounted.

The arched top 8 is provided adjacent the front or end wall G with a slot or opening l2 which .is disposed aty an angle oblique to the vertical end walls (3 and7, the side walls thereof being beveled inwardly toward their lower'ends and adapted to ex tend through the slot l2 is a metallic bridge or blast wall 18. This bridge wall is tapered thinner toward its lower end to coincide with the tapering side walls ot the opening l2, and wh'en properlyY positioned in said opening, has the lower end thereof disposed a short distance above the bottom of the furnace and in close proximity to theburner ll. .This bridge wall, therefore, divides the interior of the furnace into substantially two communicating chambers "l-'t and l5, the former representingthe co1nlnistion4 charnber. in view' ot the tacty that` the burner containel therein, while the latter may be termed a heatingehamber` as will be here inatter and more particularly dese ed. l stated, the lower end ot the brit wall t3 is disposedin close proximity to the burner ll, and thus when the liyf. lroearl1on (towing therefrom is ignited, the wall will be heated thoroughly, thereby heating `the ehamber 15, and in order to provide tor the heating of metals or other materials within said -last re'l'erred to chamber. the side 'alls 4r aud 5 are provided with elongated openings lti adjacent the bottom of thev furnace, whereby such metals maybe entered theroin.

My turnaee is particularly adapted for the heating ot rivets and the like for use in connection with boilers and other cylindrieal metallic devices, and ity will be seen thatl a number et the same may be placed in thev heating chaniber through these openings l and in View ot` the bridge wall 13, a more even heat will be thoroughly spread throughout said heating chamber. Should, for any reason whatsoever, the bridge wall become broken or otherwise danniged, the same may be readily removed, as the upper end thereof projects beyond the top ofthe furnace.

From the foregoing, it will be seen that I have provided an improved hydro-carbon furnace in which there is provided apreniovable metallic wall between the combustion and heating chambers, and thus, should it be necessary to remove said bridge wall, the same may be accomplished and replaced by another while the furnace is in operation.

It will further be seen that by providing an opening in the top of the furnace which is disposed at an angle, the bridge wall extending therethrough will likewise be diS- posed at an angle and therebydistribute the heat more evenly throughout the heating chamber, which is extremely essential in the effective operation of a furnace of this character. l i

It will still further beiseen that I have provided a furnace which is oflsuch simple -construction as to be readily and cheaply body portion from the top thereof, said wall` being disposed downwardly and forwardly toward the burner. p

2. In a furnace-of the class described, the combination with a body portion of fire brick, and a -burner extending therewithin .a short distance above the bottom of said body portion; of a' removable bridge wall extending within said body portion from the top thereof, said bridgewa'll being disposed downwardly and forwardly toward the burner to position the lower end thereof in close proximity to said burner and the bot-l tom of said body portion.

3. A furnace of the class described, comprising a body portion of fire brick, the top and side walls of which are provided with slots, a burner extendingwithin said body portion, the slot in the top of said body portion being disposed downwardly and forvwardly toward said burnerfand a bridwe wall removably mounted in the slot of said to a.

it. In a furnace of the class described, the combination with a body portion of fire brick, lthe top and side walls of which are provided with slots, and the slot in the top having the side walls thereof tapered toward their lower ends, and a' burner extended within said body portion; of a bri dgc wall extending through the slot in the, top of said body portion, said bridge wall being tapered coincident to the tapering of the side walls of said slot and having the lower end thereof disposed a short distance above the bottom of the body portion and 'in close proximity to the burner.

a In testimony whereof I hereunto affix my signature in the presence of two witnesses. l M JOHN C. SCRIVNER.
